Gaga ringing in New Year with Bennett

Lady Gaga will be performing in Sin City with her mentor December 31.

Lady Gaga will celebrate the New Year performing with Tony Bennett in Las Vegas.

The pop star recently collaborated with the 88-year-old music legend on jazz album Cheek to Cheek.

And The Cosmopolitan casino, a resort on the Las Vegas strip, announced Monday the pair will play a set of jazz standards from their album to ring in the New Year, Billboard reports.

“I can’t wait to kick off 2015 ‘cheek to cheek’ with the legendary Mr. Tony Bennett," Gaga said in a statement. “New Year’s celebrations are about cherishing family, friendship, and the future – three things this man has taught me much about.”

Tickets are scheduled to go on sale Friday.

Gaga has meanwhile been performing around the world with her mentor, Tony, calling their set in Belgium last month the “best day” of her life.

“Today is the best day of my life,” the pop star gushed on Facebook, sharing an image of her cobalt blue stage costume.

“Singing with Tony Bennett in Belgium on the eve of our Jazz album release, wearing a dress made by my best friend @brandonvmaxwell. #CheekToCheek,” she continued.

Tony is also in awe of his contemporary.

The Rags to Riches singer appeared alongside the 28-year-old star on the cover of Parade magazine last month, and shared the things he has learned from the pop star.

“Nobody has communicated with the public more than Lady Gaga. Ever,” he told the publication.

“I trust the audience, and I’m very impressed. As far as they’re concerned, she’s part of their family. The only guy who ever did that was Bing Crosby, years ago.” Copyright: Cover Media 2014
